Thanks Cliff,I'm trying to establish whether a mains cord does have to actually carry/pass current at above the mains frequency (apart from RF hash)as a result of what the amplifier itself is trying to do when complex signals are being replayed. Is it just dependent on the quality of the PSU used? Are Class A amps less prone? Shunt regulated supplies less still?
rgds,
Guy
